Definitions
- the invention is based on a display instrument according to the preamble of the main claim.
- a display instrument is known in which two displays are optically combined via a semi-transparent mirror on a display surface of the display instrument. This makes it possible to view either one of the two displays or both displays together on the display surface of the display instrument.
- the display instrument has a relatively high overall depth and also a relatively high optical attenuation, which means that the effort for illuminating the display instrument is also high.
- a display instrument in which two liquid crystal displays are arranged in front of a mechanical display instrument in which a pointer moves in front of a dial.
- the liquid crystal display facing the viewer of the display instrument serves to display information, while the liquid crystal display behind it serves as a switchable background for the front liquid crystal display.
- the rear liquid crystal display can be switched between a scattering and a transparent state.
- this display instrument also has a relatively high overall depth and a strong optical attenuation.
- the display instrument according to the invention with the characterizing features of the main claim has the advantage that it has an extremely small depth, which means the installation of the display instrument facilitated. In addition, it has a low optical attenuation, which means that the effort for illuminating the display instrument is very low.
- the formation of the first display as a pointer instrument has the advantage that a combination of a conventional pointer instrument in the motor vehicle area, for example for displaying the speed, is created with an electroluminescent display for other information which is more suitable for display on the electroluminescent display.
- the application of the dial on a light-guiding support body has the advantage that the dial undergoes mechanical mounting on the one hand and that the light-guiding support body also serves as a light guide for light for illuminating the dial.
- the overall depth of the display instrument is advantageously reduced if, in the case of an electroluminescent display arranged in front of the pointer, a recess is arranged in the support body into which the pointer projects.
- Electroluminescent display thereby a mechanically stable holder. Furthermore, optical distortions (eg parallaxes) are reduced when reading the display on the dial.
- the formation of the pointer as a disk-shaped, light-guiding body with a cutout serving as a pointer in an opaque cover layer leads to the advantage that the pointer can be illuminated particularly easily via the disk-shaped, light-guiding body.
- the pointer exerts almost no imbalance on the shaft during the rotary movement on a shaft holding the pointer.
- the training as a disc is particularly suitable for achieving a dark appearance when the pointer lighting is switched off
- the pointer is formed from a disc-shaped, opaque body which has a recess serving as a pointer
- the light from the illuminating means provided for illuminating the dial can be used simultaneously as an illuminated pointer without providing a further light-guiding body for the pointer . This reduces the effort.
- the pointer due to its approximately rotationally symmetrical shape, the pointer exerts almost no imbalance on a shaft holding the pointer.
- a pointer drive mechanism driving the pointer is fastened to a base plate together with the lighting means, the effort for holding and for powering the pointer drive mechanism and the lighting means is reduced.
- the base plate simultaneously prevents the intrusion of ambient light into the interior of the display instrument.
- the first display has an LCD display, an LED display or lighting means, since this results in a particularly flat design of the display instrument. If at least one further electroluminescent display is provided between the first display and the electroluminescent display, the display instrument can be designed with multiple displays, which gives it a particular variability.
- Electroluminescent display arranged a cover plate, so these displays are protected from environmental influences and unwanted mechanical influences.
- the cover plate is designed as a circular polarizer, the cover plate advantageously serves for the anti-reflective treatment of the surface of the electroluminescent display located within the display instrument.
- a color filter has the advantage that light falling from the outside through the cover plate into the interior of the display instrument is damped.
- FIG. 1 shows a display instrument with a disk-shaped pointer and a cover disk
- Figure 2 is a display instrument with a disc-shaped pointer and attached directly to the dial
- FIG. 3 shows a disk-shaped pointer in a top view
- Figure 4 is a display instrument with the front
- Electroluminescent display movable pointer Electroluminescent display movable pointer.
- Figure 5 is a display instrument with an LED display and two electroluminescent displays one above the other.
- FIG. 1 shows a display instrument in which a pointer drive mechanism 1, which rotates a shaft 4, is fastened to a base plate 2, the shaft 4 piercing an opening 25 in the base plate 2.
- the base plate 2 On the side facing away from the pointer drive mechanism 1, the base plate 2 has a plurality of lighting means 3.
- the illuminating means 3 illuminate a light-guiding, disk-shaped, approximately plano-convex supporting body 8, on the side of which is facing away from the illuminating means 3 and is approximately flat, an annular dial 7 is attached.
- the shaft 4 penetrates a bushing 20 in the light-guiding support body 8.
- the light-guiding support body 8 which is rotationally symmetrical, has a recess 21, which is arranged concentrically to its axis of symmetry, in which the shaft 4 runs, and which lies in the center of the annular dial 7 .
- the shaft 4 carries at its end a disk-shaped, light-guiding body 5, which is composed of two cylindrical concentrically arranged individual disks with different diameters.
- the single disk of the light-guiding, disk-shaped body 5, with the lower diameter faces the base plate 2 with a flat base.
- an opaque cover layer 10 On the opposite side carries the light-guiding, disc-shaped body 5 on the plane Base of the single disc with the larger diameter, an opaque cover layer 10, which has a cutout 11.
- the cutout 11 is designed as a radially extending slot in the cover layer 10.
- the light-conducting, disk-shaped body 5 forms, together with the covering layer 10 and the cutout 11 therein, a pointer 6.
- An electroluminescent display 9 is arranged in front of the pointer 6, which has a structured transparent layer designed as a front electrode 17 and a further structured transparent layer designed as a back electrode 19 Layer and an electroluminescent layer 18 arranged between the two electrodes 17, 19.
- the base plate 2, the light-conducting support body 8 and the electroluminescent display 9 are held together in a housing 22 which has a transparent cover plate 23 in front of the electroluminescent display 9.
- the cover disk 23 comprises a ⁇ / 4 layer 28 on the side facing the housing interior and a color filter 26 on the outside of the display instrument, as well as a linear polarizer 27 arranged between the color filter 26 and the ⁇ / 4 layer 28.
- the pointer 6 and the dial 7 together form a first display 70.
- the pointer drive mechanism 1 drives the pointer 6 in a rotary manner.
- the pointer 6 projects with the single disc with the smaller diameter of the disc-shaped, light-guiding body 5 into the recess 21. This reduces the overall height of the display instrument while maintaining the pointer stability.
- the lighting means 3 illuminate the light-guiding support body 8 from its rear. The light enters the light-guiding support body 8 and is guided by it to the rear of the ring-shaped dial 7. The light thus illuminates the dial 7 from behind.
- light from the light-guiding support body 8 passes through the depression 21 into the light-guiding, disk-shaped body 5 of the pointer 6.
- the light entering there is only guided through the cutout 11 in the direction of the electroluminescent display 9 and through the electroluminescent display 9 and the cover disk 23 to a viewer level.
- the cutout 11 appears illuminated and therefore serves as a pointer 6 with an appearance like an illuminated lance-shaped pointer of the known type.
- the lighting means 3 are switched on, the dial 7 and the pointer 6 or the first display 70 are illuminated from their rear .
- the electroluminescent display 9 is switched off in this case. When switched off, the electroluminescent display 9 is almost translucent. Thus, a viewer located in the viewer level and viewing the display instrument through the cover plate 23 can view the illuminated first display 70 through the electroluminescent display 9 and read the information displayed.
- the dial 7 and the pointer 6 are designed so that they are approximately non-illuminated from the front evenly dark area appear. Foils are available as materials for the dial 7 and the cover layer 10 (for example Macrofol foils) which show such a so-called "dead front" behavior.
- the electroluminescent display 9 can advantageously be implemented as an ACTFELD (Alternating Current Thin Film Electro Luminescent Display). This is a particularly thin version of the electroluminescent display 9. This results in a high degree of transmission when switched off
- Electroluminescent display 9 reached. In addition, the overall depth of the display instrument is reduced.
- the cover plate 23 is designed as a circular polarizer.
- linear polarization by means of the linear polarizer 27 and rotation of the polarization plane by 90 ° by means of the ⁇ / 4 layer 28, light which enters the interior of the display instrument through the cover plate 23 and after reflection on the front electrode 17 of the electroluminescent display 9 from the inside onto the cover plate 23 occurs, prevented from exiting the interior of the display instrument, which corresponds to an anti-reflective coating on the electroluminescent display 9.
- the color filter 26 preferably has a narrow-band pass band around the wavelength of the light Electroluminescent display 9, which is 585 nm (yellow) for a known thin-film electroluminescent display.
- FIG. 2 shows a further exemplary embodiment for a display instrument.
- the pointer drive mechanism 1 is in turn attached to the rear of the base plate 2 such that the shaft 4 driven by the pointer drive mechanism 1 pierces the opening 25 in the base plate 2.
- a plurality of lighting means 3 are arranged on the base plate 2, which illuminate the light-guiding support body 8.
- the light-guiding support body 8 is again designed to be rotationally symmetrical and, concentric to its axis of symmetry in which the shaft 4 lies, has the cylindrical bushing 20 which is penetrated by the shaft 4.
- a disk-shaped, light-impermeable body 12 which has the same shape as the disk-shaped, light-guiding body 5 shown in FIG.
- the opaque, disk-shaped body 12 also has a slot-shaped recess 13 which extends in the radial direction.
- the disk-shaped, opaque body 12 forms, together with the slot-shaped recess 13, an approximately rotationally symmetrical pointer 6.
- the light-conducting support body 8 has the depression 21 in which the single disk of the pointer 6 with the larger diameter, which is less than the diameter of the depression 21, is arranged is, the pointer hub 24, the diameter of which falls below the diameter of the bushing 20, pierces the bushing 20.
- the flat surface of the light-guiding support body 8 facing the viewer projects beyond the flat surface of the disk-shaped, opaque body 12 facing the viewer.
- the circular dial 7 is attached to the surface of the light-guiding support body 8, thereby forming a cover for the depression 21.
- the electroluminescent display 9 is applied directly on the upper side of the dial 7.
- the electroluminescent display 9 comprises the rear electrode 19, the front electrode 17 and the electroluminescent layer 18 arranged between the two electrodes 17, 19.
- the electroluminescent display 9 together with the dial 7 and the light-guiding support body 8 thus forms a solid, approximately plano-convex unit. This unit, like the base plate 2, is held in the housing 22.
- the pointer 6 and the dial 7 in turn form the first display 70.
- the lighting means 3 in turn serve to illuminate the light-guiding support body 8, which guides the incoming light to the dial 7.
- the slot-shaped recess 13 in the disc-shaped, opaque body 12 is used for the transmission of light emerging from the light-conducting support body 8 towards the viewer and thus causes the appearance of an illuminated pointer 6.
- the display in FIG Case appearing transparent
- the electroluminescent display 9 enables the first display 70 and the information displayed thereon to be viewed directly.
- the lighting means 3 are switched on.
- the lighting means 3 are switched off, and the dial 7 and the pointer 6 appear as an almost uniformly dark background area for displaying the further information on the electroluminescent display 9.
- This is done in a known manner by activating the electrodes 17, 19 it is particularly expedient to design the electroluminescent display 9 as an ACTFELD, since this results in a particularly small overall depth of the display instrument.
- the pointer 6, which is completely embedded in the contour of the light-guiding support body 8, also results in a further reduction in the overall depth and an improvement in the reading accuracy of the display instrument.
- FIG. 3 shows a top view of the pointer 6. It can be seen that the pointer 6 is approximately rotationally symmetrical, the symmetry being interrupted only by the radially outwardly extending slot-shaped recess 13 in the disc-shaped, opaque body 12. Due to the approximately rotationally symmetrical shape, the pointer 6 exerts only an extremely small bending moment on the shaft 4 when accelerated by the shaft 4 driving the pointer 6, as a result of which the display accuracy and the Life of the display instrument is extended. In addition, the required "dead front" appearance can be achieved particularly well since the pointer 6 has a large surface which, when mounted on the support body, only requires a small annular slot between the support body 8 and the pointer 6, which could cause an inhomogeneity in the appearance.
- FIG. 4 shows a third exemplary embodiment of the display instrument. Again, the numbering of the individual elements according to FIGS. 1, 2 was retained.
- the pointer drive mechanism 1 is mounted on the rear side of the base plate 2, the shaft 4 driven by the pointer drive mechanism 1 rotatingly penetrating the opening 25 in the base plate 2.
- a plurality of lighting means 3 are arranged, which illuminate the light-guiding, approximately plano-convex support body 8.
- the dial 7 is applied to the light-conducting support body 8 on the side facing away from the illuminants 3.
- the dial 7 and supporting body 8 have the cylindrical bushing 20 through which the shaft 4 projects.
- the light-conducting hub 15 also pierces a cylindrical hole 16 which is present in the electroluminescent display 9.
- the electroluminescent display 9 consists of three layers, the electroluminescent layer 18 being arranged between the rear electrode 19 and the front electrode 17.
- the electroluminescent display 9 is applied over the entire surface of the dial 7.
- the cover plate 23 is arranged in front of the electroluminescent display 9 and the pointer 6, which, like the one connected to the dial 7 and the light-conducting support body 8 Electroluminescent display 9 and the base plate 2 is held in a housing 22. Again, the pointer 6 and the dial 7 form the first display 70.
- Light emanating from the illuminating means 3 illuminates both the light-guiding support body 8 and the light-guiding hub 15 from the rear thereof.
- the light entering the pointer flag 14 is guided through the light-guiding hub 15, as a result of which it is illuminated.
- the dial 7 is illuminated from behind by the light entering the light-guiding support body 8.
- the luminous pointer 6 can thus be seen in front of the illuminated dial 7 through the cover plate 23 when the electroluminescent display 9 is switched off and is therefore translucent.
- the dial 7 appears as an approximately dark background area for the electroluminescent display 9. Since the pointer 6 consists of a light-conducting, otherwise almost transparent material, it also interferes with the display of the further information by the electroluminescent display 9 when the illuminants 3 are switched off only to a negligible extent. Since the electroluminescent display 9 is applied directly to the dial 7, the overall depth is reduced, on the one hand, and on the other hand, almost no optical distortions occur even with an oblique viewing angle. In the case of simultaneous display of information by means of the dial 7 and further information on the electroluminescent display 9, the parallax error is also very small. Again, it is expedient to use the electroluminescent display 9 as an ACTFIELD to execute. Likewise, it is also provided here in turn to design the cover plate 23 as a circular polarizer with a color filter 26 and in an inclined position.
- FIG. 5 an arrangement is shown in FIG. 5, which differs from the arrangement shown in FIG. 1 by the following differences: in front of the first display 70, two electroluminescent displays 9, 69 are arranged in the housing 22 here, the first display 70 is designed as an LED display. As a result, the lighting means 3, the base plate 2, the support body 8, the pointer 6, the dial 7 and the pointer drive mechanism 1 are omitted here.
- This display instrument is thus suitable for displaying different information on each of the displays 70, 9, 69 by switching between the three displays 70, 9, 69.
- the three displays 70, 9, 69 are switched on, while the other two displays 70, 9, 69 remain switched off. Since the electroluminescent displays 9, 69 appear transparent when they are not being driven, an unobstructed view of the display 9, 69, 70 that is currently being operated is always possible. Conversely, the LED display 70 forms a dark background if one of the two electroluminescent displays 9, 69 is used to display information.
- a series arrangement of several electroluminescent displays 9, 69 is also provided, behind which the first display 70 is at least partially arranged, which is temporarily illuminated and thereby visible, but also temporarily unilluminated and darkly switchable.
- a such a series arrangement can even be used to display information in three-dimensional form, in that the electroluminescent displays 9, 69 and possibly also the first display 70 are operated simultaneously.
- the first display 70 need not necessarily comprise a pointer instrument. It can also include an LCD or LED display or any type of illuminant that meets the condition of forming a dark background for the electroluminescent display 9 in a non-informational state.
- the cover plate 23 can also be designed as a normal, transparent plate.
